C-18 A view down the MoPPh2 2 molecule, showing the internal rotation. The ligand has the S configuration at each asymmetric carbon atom thus giving rise to only one of the two helical conformations about the Mo—Mo bond.

C-19 is a photo of an intermediate size disk nozzle centrifuge. This machine is fitted to operate tmder elevated temperature and pressure conditions and for the purification of terephthalic acid crystals. Note the electric motor, the overhead V-belts, and the flexibly moimted bearing assembly. These power the pendulum-suspended rotor, which has somewhat of a double cone shape with the nozzles located at the largest peripheiy. The housing material is Hastelloy for extra corrosion resistance and the rotor is similarly special to withstand the severe mechanical and chemical conditions.

C-2 The structure of the dichromate ion as found in Rb2Cr207.

C-20 is a cutaway view of a disk nozzle centrifuge that shows the flow pattern. It is easy to follow the path of the feed slurry as it flows continuously down into a central rotating feed distributor and laterally into the main separating chamber. Here the high sedimenting force back to a reinjection port in the bottom of the stationary housing and jets back into the rotor hub where it is reaccelerated.

C-20 Some reactions of Mo and W compounds with metal-to-metal triple bonds.

C-21 is a cutaway view of the centrifuge with a special wash inlet system inserted at the bottom of the housing. This system makes it possible to inject large volumes of wash at the interior of the rotor where the flow must travel inwardly and countercurrently to the outward motion of the solids. This action can accomplish a great increase in the washing capability of a sii le stage or it can significantly enhance the sharpness of the separation between two classes of solids.

C-21 Some reactions of the doubly-bonded W2.
